Somatotype (Ectomorph/Mesomorph/Endomorph) Calculator

Determine your somatotype to understand your body type and optimize your training and nutrition approach.

Somatotype Calculator

Classify your body type (Ectomorph/Mesomorph/Endomorph) based on anthropometric measurements to guide training and nutrition.

Understanding the Inputs

Collect accurate measurements for meaningful results

  • Height & Weight: Used to calculate BMI and height-to-weight ratio, which contribute to ectomorphy (linearity) and endomorphy (adiposity) scores.
  • Wrist Circumference: Measured around the narrowest part of the wrist. Indicates bone structure and contributes to mesomorphy (muscularity) score.
  • Ankle Circumference: Measured around the narrowest part of the ankle. Also indicates bone structure and contributes to mesomorphy score.
  • Gender: Men and women have different somatotype distributions. Men tend to score higher in mesomorphy, while women may score higher in endomorphy.
  • Age: Somatotype can change with age due to muscle loss, fat gain, or lifestyle changes. Training and nutrition can influence all three components.

Complete Guide: Understanding Somatotypes

Evidence-based strategies for body type optimization

Somatotypes are a classification system for human body types based on three components: ectomorphy (linearity), mesomorphy (muscularity), and endomorphy (adiposity). Each component is scored on a scale of 0–7. Most people are combinations of types rather than pure examples.

While genetics play a role, training and nutrition can significantly influence all three components. Ectomorphs can build muscle with proper training and nutrition, endomorphs can lose fat and build muscle, and mesomorphs can optimize their natural advantages. Use your somatotype as a guide, not a limitation.

Frequently Asked Questions

Common questions about somatotypes and body types

What are somatotypes?

Somatotypes are a classification system for human body types based on three components: ectomorphy (linearity/thinness), mesomorphy (muscularity), and endomorphy (adiposity/fatness). Each is scored 0–7.

What is an ectomorph?

Ectomorphs are naturally thin, lean individuals with long limbs, narrow frames, fast metabolisms, and difficulty gaining weight or muscle. They typically excel in endurance activities.

What is a mesomorph?

Mesomorphs are naturally muscular, athletic individuals with broad shoulders, narrow waists, and the ability to gain muscle easily. They typically excel in strength and power activities.

What is an endomorph?

Endomorphs are naturally soft, round individuals with wider frames, slower metabolisms, and the ability to gain weight easily. They have good potential for building muscle mass.

Can I change my somatotype?

While genetics play a role, training and nutrition can significantly influence all three components. Ectomorphs can build muscle, endomorphs can lose fat, and mesomorphs can optimize their natural advantages.

What is the best somatotype for athletes?

It depends on the sport. Mesomorphs excel in strength/power sports, ectomorphs in endurance sports, and endomorphs in strength sports requiring mass. Most people are combinations.

How accurate is somatotype analysis?

Somatotype analysis provides a useful framework but is not definitive. Most people are combinations of types, and training can shift scores over time.

What training is best for each somatotype?

Ectomorphs: compound movements, caloric surplus, limited cardio. Mesomorphs: balanced approach, moderate volume. Endomorphs: higher volume, include cardio, monitor nutrition closely.

Can women be mesomorphs?

Yes, though women typically score lower in mesomorphy than men due to hormonal differences. With training, women can develop significant mesomorphic characteristics.

Do somatotypes change with age?

Yes. Muscle mass declines (lower mesomorphy), fat may increase (higher endomorphy), and bone structure changes can affect all three components. Training can mitigate these changes.
